LIQUID-CIRCULATING APPARATUS FOR INTERNAL-OOMBUSTION MOTORS.

Application filed March 3, 1926.

This invention relates to an improved water pump, designed to be installed in the liquid circulating system 01 an automobile, being especially, although not necessarily, designed for use on Fords.

The principal object of this invention is to provide a simple, economical and durable Water pump which is such in construction that it can be installed by inexperienced persons.

A further object is to provide a pump of the class under -consideration which is driven by the fan belt of the engineand which communicates with water ways in the cylinder block and is secured to the cylinder block in the same manner and by the same studs that originally served to retain the water return pipe in position.

A further object is to provide a water pump which will support the electric horn of the automobile either for models before or after the year 1925/ A further object is to provide a water pump which may readily be taken apart for repairs or adjustment.

These and other objects will be apparent to those skilled in the art.

My invention consists in the construction, arrangement and combination of the various parts of the device, whereby the objects con-, templated are attained as hereinafter more fully set forth, pointed out in my claims and illustrated in the accompanying drawings, in which:

Fig. 1 is a side view of my'complete device ready for use and mounted on an internal combustion motor with parts cut away to more fully illustrate the same.

Fig. 2 is a top plan view of my water pump mounted on an internal combustion motor with sections cut away to more fully illustrate the same.

Fig. 3 is an end sectional view taken on line 33 of Fig. 1 and shows the rotor mounted in the pumpcasing.

Fig. 4 is a sectional view taken on line 4-4 of Fig. 1 and shows the means of actu ating the pump.

Fig. 5 is a back view of an electric horn for models prior to the year 1925 and shows the manner of securing the same to the top of the cylinder casing and my improved water pump.

Fig. 6 is a side View of an electric horn for models during and since the year 1925 Serial No. 91,969.

and shows the manner of securing the same to my improved water pump.

The thermo-siphon cooling system, such as is extensively used in connection with internal combustion motors at the present time, is not effective in maintaining the engine at a proper temperature under all conditions of service, due to the fact that the cooling liquid circulates through the system very slowly and hence the engine heats up rapidly, and is further not effective due to the fact that all circulation in the system ceases upon a drop in the level of the cooling liquid to a point below the radiator inlet. Two classes of devices have been designed to overcome these defects by forcing the circulation of the cooling liquid, one class of said devices utilizing the exhaust of the engine while the other class utilizes a mechanical impelling device. My device relates to the last mentioned class.

In mounting the mechanical impelling devices now on the market to the cylinder block, the position of the electric horn is obstructed. I have also overcome this objection as will hereafter be explained.

I have used the numeral 10 to designate the ordinary internal combustion motor hav ing water ways for keeping the same cool. At the top of the engine and communicating with the water ways and radiator 11 is the 1 circulation elbow 12. Rotatably mounted on the fan shaft 13 and back of the radiator is the fan 14. The numeral 15 designates an endless belt in engagement with the crank shaft 16 ot the engine and the fan 14. In the side of the cylinder blocks of the engine is a port 17 communicating with the water ways around the cylinders. Ordinarily this port is also in direct communication by a conduit to the bottom of the radiator 11. It is between this port and the bottom of the radiator that I install my improved pump.

The numeral 18 designates the cylindrical block. Originally these studs held the ordinary water connection which was in communication with the bottom of the radiator. Forwardly and outwardly extending and integrally formed on the flange 24 is the arm 25 having integrally formed on its end the bearing member 26. Inside this bearing member 26 is a wooden bearing 27. The front end of the pump casing 18 restricted and forms a bearing member 18 which has threaded into its opening the gland 28. Passing through the wooden bearing 27, the gland 28 and into the pump casing is the pump driving shaft 29 jour'naled for rotation. On the end of the shaft 29 within the pump casing is the rotor 30. ()n the other end of the shaft 29 is the pulley wheel 31 designed to engage the fan belt 15 as is shown in Fig. 4 and Fig. 1. This pulley wheel may be slid on the shaft 29 to a position where it is in proper alignment with the fan belt. Once it is in proper alignment it may be secured against any relative movement to the shaft by tightening the set screw 32. To prevent the shaft 29 from being pulled from the pump casing a collar 33 is provided and is secured to the shaft by the set screw 34 and positioned ad acent the bearing member 26 as is shown in Fig. 2. To prevent unnecessary friction a washer 35, preferably made of wood, is placed between the collar 33 and the bearing member 26. The numeral 36 designates a rubber hose employed to secure the pipe 37 to the inlet pipe 19, and the numeral 38 a second rubber hose employed to secure the pipe 37 to the bottom of the radiator.

It will now readily be seen that if the engine is running, the shaft 29 will be rotated; which in turn rotates the rotor 30. This action draws the cooling liquid from the bottom of the radiator and deposits the same into the port 17, thus forcing the circulation of the cooling medium.

To prevent the leakage of the cooling medium from the front end of the pump casing, packing 89 is placed in the bearing member 18 and around the shaft 29. This packing is held in place by the shoulder 10 in the bearing member 18 and the gland 28. By screwing the gland 28 to the right the packing will be compressed and held tightly around the shaft and against the bore of the bearing member.

To guard against unnecessary movement and possible displacement of the device after it is once positioned, and also to decidedly increase the rigidity, I make use of the stud 41 in the arm 25, which is designed to be brought against the cylinder block. This stud is held against rotation by the lock nut 42.

In the bottom of the pump casing and communicating with the inlet pipe 19 is the hole 43. This hole is provided so that when the radiator is drained to prevent freezing, the pump casing will also be completely drained. Thus no water will remain in the casing and freeze and hinder the effective rotation of the member 30.

Vihen the device is installed on automobiles purchased before 1925 and having the old style electric horn bracket 14-, the same is bent outwardly as is shown in Fig. 5 until the lower portion of the bracket embraces the lug integrally formed on pump casing. This end of the bracket is held on the lug by the stud 16 passing through the same and threaded into the said lug.

When the device is installed on automobiles having the new style electric horn bracket 47, the same is secured to the water pump by the stud 18 passing through the bracket and threaded into the projection 49 integrally formed on the pump casing, and the stud 50 also passing through the bracket and threaded into the car 51 formed on cover plate 22, as is shown in Fig. 6.

I have used the numeral 52 to designate the ordinary electric horn.

Some changes may be made in construction and arrangement of my liquid circulating apparatus for internal combustion motors without departing from the real spirit and purpose of my invention and it is my intention to cover by my claims any modified forms of structure or use of mechanical equivalents which may be reasonably included within their scope.
